Montero Mining and Exploration Provides Update From Test Work from the Wigu Hill Rare Earth Project in Tanzania

Montero Mining and Exploration Ltd. (TSXV:MON) announced updates on the study done on the bastnaesite-rich carbonatite material from the Wigu Hill Rare Earth Project in Tanzania.

As quoted in the press release:

 In laboratory scale test work, flotation tests were completed to evaluate various collector types and dosages. The best results from rougher stage tests were achieved from a head grade of 6.42% Ce₂O₃ using a hydroxamate-type collector. Here, the cumulative rougher concentrate graded 12.8% Ce₂O_3, with 79.1% recovery and 48.1% mass pull which represents x2 upgrade. A collector was also selective against barite, quartz, Fe-oxides, and dolomite. The results achieved in the scoping study demonstrate the potential to recover REE minerals into a pre-concentrate and reject the major gangue minerals, which are acid consumers for the downstream hydrometallurgical process.

Montero’s President and CEO,  Tony Harwood, said:

Advancing the mineral processing flowsheet with the flotation testwork completed by SGS-Lakefield, keeps us on a production focused target for our flagship Wigu Hill project. These positive results represent a significant step in advancing the beneficiation process and improving Montero’s economic flowsheet for the extraction of REEs from the bastnaesite-rich carbonatite mineralization. By reducing downstream reagent consumption costs we are on track to becoming a low cost producer of Rare Earths.
